To all whom it may concern.-

Be itknown that I, LAZARD KAHN, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Gas- Stoves, of which the following is a specification.

My improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figurel is aperspective viewof a gas-stove exemplifying my invention; Fig. 2, a perspective view of the cake-griddle removed from the stove and turned around so that its rear edge can be seen; Fig. 3, a perspective View of the stove of Fig. 1 as it appears when the cake-griddle is removed; Fig. 4, a plan of the stove-body; Fig. 5, a plan of the burners detached; Fig. 6, a plan of one of the grids detached; Fig. 7, a vertical transverse section of the stove-body in the plane of line a of Fig. 4, and Fig. 8 a plan of the fillershelf.

In the drawings, 1 indicates the stove-body in the form of a table-like structure supported on legs; 2, large openings through the stove-body, the number of these openings corresponding with the number of burners with which the stove is to be supplied, (three in the exemplifioatiom) the openings being considerably larger than the burners; 3, the burners disposed centrally within the openings 2 and with their tops at about the level of the top of the stove-body; 4:, ahollow shank projecting forwardly from each burner below the top of the stove-body and extending be yond the front of the stove-body, this shank forming the gas-conduit to the burner; 5, the gas-cocks secured in the forward ends of the hollow shanks 4; 6, the supply-pipe rigidly connected with all of the burner-cocks in the usual manner and extending along as a rail in front of the stove-body, one end of this pipe being fitted as usual for connection with the tube which is to bring the supply of gas to the stove; 7, tail-shanks projecting rearwardly from the burners far enough to reach under the rear margins of the openings 2 in the stove-body; S, a loop or mortise formed in the rear margin of each of the openings 2 below the top of the stove-body in position to be engaged by the tail-shank 7 9, upwardly open notches in the front wall of the stovebody in the front margins of the openings 2 in position to receive the front shanks 4 of the burners; 10, lugs upon the front and tail shanks of the burners engaging inwardly against the loop 8 and inwardly against the front wall of the stove-body at the foot of the notches 9, these lugs preventing the endwise shifting of the burners; 11, a grid, one for each of the openings 2, these grids resting on the top of the stove-body and forming a raised margin for the burner-openings; 12,a notched lug upon the front of each grid, projecting downward at the front wall of the stove-body and engaging the front shank of its burner and forming an escutcheon therefor; 13,11ooklugs projecting sidewise from the bottom of one of the side margins of the grid; 14, notches in .one of the sidemargins of each of the burner-openings 2, these notches adapted to be engaged by the hook-lugs 13 of the grid; 15, a bolt through the grid and stove-top at the side margin of each grid opposite the hook-lugs 13; 16, a cake-griddle having a flat upper surface and having a surrounding ourtain, the dimensions of the griddle and the depth of the curtain being such that when the griddle is placed upon the top of the stove the curtain will rest upon the top of the stove and fit the outside of and completely inclose the grids; 17 notches in the rear edge of the curtain of the griddle in such longitudinal position as to come between the grids, it being understood that the cake-griddle as it appears in Fig. 2 is in reverse positionthat is to say, the rear of the griddle appears in frontthe front curtain of the cake-griddle having only such notches as are requisite to forms a selfecontained structure. The cakegriddle and grids being off of the stove, the burner structure is readily put in place as a unit by presenting the rear shanks 7 .to the loops 8 diagonally, and then by a hinge-like motion dropping the front of the burner structure into the notches 9, the stove-body then giving rigid support to the burner structure, which may be easily removed for cleaning. The grids are put in place by engaging the hook-lugs 13 with the notches ll by hingelike action and then applying the screws 15, the escutcheon then holding the front of the burner structure down into the stove-body, the escutcheon at the same time forming an ornamental projection at the front edge of the stove-body. The grids are in effect hinged to the top of the stove and may be readily turned up to get at the burners for cleaning, the. The bolts 15 secure the free edges of the grids to the stove-top and prevent displacement of the grids while shipping, sellin g, &c., and at times when the stove is out of such use as requires the opening up of the grids. The cake-griddle may be applied and removed as desired for use in baking, and also for use in forming a neat projecting cover for the top work of the stove when the burners are not use, thus guarding against the fouling of the burners by non-use and presenting a table-like surface of frequentconvenience. \Vhen the griddle is in use for baking, the hot products of combustion leave through the notches 17, which, being disposed longitudinally between the burners, direct the heatingcurrents sidewise from the burners and eifect a more even heat of the entire surface of the cake-griddle, and avoid the common evil of a cake-griddle highly heated at spots directly over the burners.

In gas-stoves of this character with gridwork projecting upwardly from the surface of the stove it is possible to employ large vessels and get a large spread of flame where heavy work is to be done. This is the main merit of elevated grids. But for lighter work, with either large vessels or groups of small ones, the elevated grid becomes a disadvantage by failing to give support to overhangin-g vessels and by admitting cool air where it is undesirable to where it is desirable when working with low flames. In my improved stove the elevated grids may in effect be present or absent, as desired. When the fillerplates are in place between the grids, the grids cease to be elevated grids and a level table-like surface is provided for the support of the vessels. The filler-plates are readily removed, rendering the elevation of the grids effective.

I claim as my invention- 1. The combinationof a stove having a se ries of burners, a griddle having a curtain margin resting upon the stove, said curtain having cut-away portions intermediate of and substantially equidistant from the burners, whereby the products of combustion from the burners will be confined and deflected to uniformly heat the entire under surface of the griddle.

2. In a gas-stove, a table-like stove-body provided with burner-openings in its top and perforated intermediately of said openings, grids elevated above the stove-body, and detachable filler-shelves adapted to rest upon the inner edges of the grids and bridge across the space between the grids and lie flush therewith, and adapted to be attached to the rear of the grids to form shelves, all substantially as set forth.
